There is the famous line "No man is an island, entire of itself." A good quote; hard to imagine it being put to bad use. The line comes from Devotions Upon Emergent Occasions, 23 meditations that Donne wrote on what he thought was his deathbed. (There's another line further down in the paragraph that's also famous, though only because Hemingway used it for the title of his novel For Whom the Bell Tolls.)
